Renewed July 20, 1928.

This invention relates to printing machines and more particularly to a form of printing machine adapted to produce mailing wrappers, such as used for newspapers and pamphlets and to print addresses thereon.

One object of this invention is to provide an efficient rapid automatic means for making mailing wrappers of various desired lengths for magazines, newspapers, catalogs and the like, from a continuous roll of paper stock.

Another object of this invention is to provide means in a machine of the above character for imprinting upon the wrappers the addresses of the subscribers or intended recip ients thereof and also the return address of the sender.

A further object is to provide means for printing a convenient form of checking list or proof strip having a copy of each address as printed upon the wrappers.

Another object is to provide a means for automatically selecting the particular addresses that are desired to be used at any time, from a large number of addresses included in the general mailing list.

Another object is to provide automatic means for placing a distinguishing mark upon certain wrappers to indicate that these wrappers are the first or last of certain groups of wrappers, which groups are thereby distinguished from other wrappers printed from the same mailing list.

A still further object ofithis invention is to provide a machine of the character above indicated, which is reliable in operation, comparatively inexpensive of manufacture and which requires very little attention for its proper operation and upkeep.

Among the principal elements of the structure shown in the drawings are, a frame A- to which the various parts of the entire machine are attachecha roll of wrapper paper stock B, an impression arm and mechanism (1 (Fig. 2), under which paper from the stock roll B is drawn by feed rolls D-, a mechanism at -E for feeding through the machine a group of address plates from which impressions are taken upon the wrapper paper by the impression mechanism C and a cutting-off machine F for cutting the paper stock into the desired wrapper lengths. A roll Gsuppl1es the necessary paper stock upon which an impression arm and mechanism -H (Fig. 2) prints a checking listor proof-strip from the, address plates as fed through the mechanism at E-. A proof-strip Winding mechanism is shown at I. An impression arm and mechanism at J (Fig. 2) serves to print a return address upon each wrapper. The mechanism at K (Fig. 2, also Figs. 33-35 inclusive) serves to place a distinguishing mark upon certain wrappers which represent the beginning or ending of a special group of addresses. Power for operating the entire machine is supplied by a motor L.

The path along which the stock travels from the roll -B- will now be described more in detail.

W Vrapper paper stock 40 in the form of a I long band "of paper of a width equal to that stock roll Bunder and around a tension roller 47 ,up over guide bars 48 and 49, and

between an address mat guiding mechanism 50'and the. impression ar1ns' at-G-'H- and J, (Fig.2), by paper feed rollers 51 and 52 (Fig. 11) and is then pushed on through the cut-off mechanism where the paper 40 is cut into separate wrappers.

The feed rollers 51 and 52 are mounted upon shafts 53 and 54, respectively, which are suitably journaled in the side frames 45 and 46, as best shown in Figs. 1 and 9. The

bearings for the shaft 53 may be similar at each end of the shaft and preferably comprise, as shown in Fig. 9, a bearing block 55 retained in a slot 56, formed in the frame 45. The bearing block 55 is preferably retained beneath a spring 57, acting between the top of the block 55 and a'spring retaining disc The height of the spring retaining disc 58 may be adjusted a screw 59, having a lock nut 60 and extending through a plate 61 fastened to the frame 45. By turning the screw 59 downwardly, the pressure of the spring 57 upon the bearing 55, and consequently also the pressure of the rollers 51 against the opposing rollers 52 is increased. To decrease the pressure .between the rollers 51 and 5-2, the screw 59 is adjusted upwardly.

The shafts 53 and 5.4 may be retained in their proper longitudinal position in the" Journals by collars as shown at 62 and 63, respectively. The bearing blocks 55 are provided with flanges as at 64 (Fig. 10) for retaining the blocks between the side frames 45 01:46 and the collars 62. r

The peripheries of the feed rollers 51 are preferably circumscribed with rubber coverings 65 (Fig. '11) in order to aid in gripping the paper 40.

ear b a' luralitv of screws 71. The )lIllOIl s y l 69 is positioned upon'thehub 68 by a collar 73 provided with a 'set screw 74. A pawl 75 is pivoted'on a screw 76 to thegear 67 and is held in engagement with the ratchetby a pawl spring indicated in Fig. 6.

Meshing with the pinion 69 is a gear segment 77, which is fixed upon a pin 78 pivoted in the side frame 45 (Fig. 6), and is connected by a connecting rod 7 9 to a crank 80. The crank 80 is mounted upon a 'shaftSl and is rotated thereby. The shaft 81 is rotated by means ofa train of gears 82,83 and 84,'each mounted upon the side frame 45 (as appears in Figs. 5 and 6) and which in turn are rotated by a pulley 85 fixed to the gear 84 and connected to any suit-able source of'power, preferably by a belt 86 to the motor -L,

as shown. Y

' As the shaft 81 and the crank 80 are rotated in a clockwise direction, the connectin rod 7 9 at first moves the segment 77 to the Teft (in Fig. 6) and thereby tliepinions 69 is also rotated in a clockwise direction and the attached ratchet 7O willride'underthe pawl 75. However, upon the completion of the stroke of the crank 80, the gear segment'77 will be drawn to the right and hence the pinion (59 will then be rotated in a counter-- clockwise direction. Under this latter condition, the pawl will engage the ratchet 70 and as a consequence the gears 66 and 67 and the rollers 51 and 52 will be rotated. The paper 40 will thus be advanced a predetermined distance upon each stroke of the gears segment 77.

Since wrappers of various sizes or lengths are sometimes desired, provision has accordingly been made to increase or decrease the travel of the feed rollers 51 or 52 by lengthening or shortening the travel of the gear segment 77. This is accomplished by adjusting the effective length of the crank between the shaft 81 and the pivoting point 87 of the crank 80 with the connecting rod 79. The means for making this adjustment is best shown in Fig. 7. The crank 80 is provided with a slot 88, which is engaged by head 89 of a pivoting bolt 90. The bolt 90 passes through a bushing 91 which in turn passes through the end of the crank 79. The crank 79 and the bushing 91 are retained upon the bolt 90 by a washer 92 and a nut 93, the nut 93 serving to clamp the bushing 91 firmly against the crank 80. In order to change the position of the connecting rod pivot 87, it is merely necessary to loosen the nut 93 and the entire pivot may then be moved to the desired position along the slot 88, at which point the nut 93 is again tightened.

To avoid any possible sudden pull, sulficient to tear the paper stock 40 by abruptly starting the feed rollers 51 and 52, the power on the feeding stroke of the connecting rod 79 is transmitted to the gear segment 77 through the medium of a spring 94 (see Fig. 8). The spring 94 is mounted at the end of the connecting rod 79, one end pressing against gear segment spacing blocks 95 and 96 and the other end pressing against a spring retaining disc 97, which is held in adjustable position in relation to the connecting rod by a bolt 98 and a nut'99. A. pin 100 passing through a slot 101 in the connecting rod 79 and also through the spacing blocks 95 and 96 serves to pivotally attach the con necting rod to the gear segment 77 at this point.

As the connecting rod 79 starts on the feeding stroke toward the right in Fig. 6, the spring 94 is compressed at first and hence the segment 77 is given an easy and gradual start. This action avoids the danger of tearing or straining the paper 40 which would result if rigid connections were used between the connecting rod and the gear segment.

The tension relieving roll 47 is mounted in side arms 102, which are pivoted upon the frames 45 and 40, as at 103, (Fig. 1). The side arms 102 are pulled downwardly by coil springs 104 which are attached to the frame A in any suitable manner as by pins 105. The downward travel of the arms 102 is limited by stop springs 106 mounted upon the frame A. As the paper stock 40 is drawn forward by the feed rollers D, the stock roll B- must also be rotated. The roll -B having a large mass, possesses considerable inertia. Hence, in order to start suddenly the rotation of the roll from a position at rest, a large force is necessary. Such a force at times would be too great to be safely transmitted by the band of paper stock 40. Therefore, the tension relieving roll 47 may be used to allow a more uniform rotation of the roll B, the coil springs 104 serving to absorb any jerking movements that are imparted to the paper by the feed rollers D.

Figs. 3 and 4 show the type of address plates or mats 107 which are used in the machine. The mats 107 are stacked in a rack 108 in the order in which it is desired to print the various addresses upon the wrapers.

p The address plate guiding mechanism 50 is illustrated in detail by Figs. 12 through 17 35, 37 and 38. The side frames 45 and 46 are provided respectively with a pair of supporting brackets-109 and 110 (see Fig. 2), which serve to support the ends of side bars 111 and 112, forming part of the guiding mechanism 50. The brackets 109 and 110 are fixed to the side frames 45 and 46, respectively, by screws 113 and 114. The side bars 111 and 112 are attached to the brackets 109 and 110. respectively, by screws 115 and 116. The address plates are adapted to slide one by one from the rack 108 along between the side bars 111 and 112 and upon a support bar 117, which is mounted upon posts as at 118. The posts 118 rest upon cross strips, as at 119, fastened to the underside of the side bars 111 and 112 by screws 120. The support bar 117 is held in place upon the posts 118 by screws, as at 121, which extend through the posts and into the cross strips 119 (see Figs. 12 and 16).

The support bar 117 is also supported at its end 122 by a screw 123, which passes through a plate 124 and into the end 122. The end 122 and the plate 124 are maintained in their proper relatively spaced positions by a washer 125, as shown in Fig. 12. The plate 124 may be fixed to the side bars 111 and 112 by screws 126.

A feed block 127 is adapted to be reciprocated between the side bars 111 and 112 by a connecting rod 128 which is pivoted to the block within a slot 129 by a pin 130. The connecting rod 128 extends downwardly and across the machine, as shown in Figs. 5 and 11, to a rotataale disc 131 to which it is pivotally and eccentrically connected by a lug 132 through which a screw 133 passes into the disc 131. The disc 131 is fixed to a shaft 134 ice which in turn is journaled in a bearing 35 attached to the side frame 46. At the other end of the shaft 134, a bevel gear 136 is fixed for meshing with a bevel gear 137-, xed upon the shaft 81. The gears 136 and 137 may be both providedwith the same number of teeth.

It will thus be seen that as the shaft 81 is rotated in the manner above described, the shaft 134 will also rotate together with the disc 131 which will cause one forward and backward movement both of the rod 128 and the block 127 for each revolution of the shaft 81. Hence for each advancement of the paper stock 40 by the feed rol s 51 and 52, a new address plate may be advanced bythe block 127.

The path of travel of the address plates will now be further described. The rack 108 comprises a pair of U-shaped guides 138 and 139 which are maintained in upright position over the guideway 50 by brackets 140 and 141, respectively, having slotted foot portions as at 142 (Fig. 5) engaged by screws 143 extending into the side bars 111 and 112. The rack may be removed as will readily be understood by simply raising the slotted foot portions out of engagement wit-h the screws 143.

The lower address plate 107 within the rack 108 rests upon the support bar 117. Sufficient space at 144 (Fig. 12) is leftbctween the lower end of the rack 108 and the bar 117 to permit a single address plate to be slid from under the rack and along the guideway by the action of the reciprocating block 127. Mat pushers 145 and 146 are secured to each side of the block 127 by screws 147 and serve to engage the depressed edges as 148 and 149 of the address plates or mats 107 and thereby slide the plates out from under the rack 108. The plates are slid further along the guideway by the action of a push bar 150 which is also attached to the block 127 by screws 151 and reciprocates therewith.

The push be 150, and the mat pushers 145 and 146' slide upon supporting bars 152 and 153 fixed to the underside of the side bars 111 and 112, respectively, by screws 154. "These supporting bars, as will be seen, thus also serve to slidably support the blcck 127. (Fig. 17.)

The push bar 150 is provided along its side with a plurality of pawls 155 pivotally mounted on pins 156 and normally held in active position by springs 157 which press the pawls into contact with stop pins, as at 158. The pawls are adapted to engage the depressed edge 148 of the address plates 107' in a manner similar to the action of the mat pusher 145 and each pawl serves to advance an address plate for a distance equal to the spacing between plates along the guideway for each reciprocation of the block 127. ()n

he return movement of the block 127 and the push bar 150, the pawls 155 slide freely under the address plates by reason of the yielding of the springs 157, and at the same time the plates are checked against any possible backward travel, as would be caused by friction against the pawls, by stop springs 159. The forward movement of the plates meets with no resistance, since the stop springs are depressed as the plate slides .thereover. Upon forward movement, the friction between the stop springs and the address plates serves to prevent the plates from being thrown too far ahead, as would possibly happen if the plates were permitted to travel freely in the guideway. The stop springs 159 are fixed to the underside of the support bar 117 by screws 160 and extend up through openings 161 in the support bar.

The address plates are retained upon the support bar 117 by flange strips 162 and 163 fastened to the side bars 111v .and 112, repectively, by screws asat 164 (Fig. 16). A spring 165 fixed to'the bracket 141 makes frictional. contact with each plate as it leaves the rack 108 and prevents any possible excess travel of the plates at this point.

After the desired printing has been done by the impression mechanisms .H-, -C- and -J, the address platesare pushed on into a discharge galley 166, shown in Figs. 18, 14, 15 and 37. The discharge galley comprises a frame member 167 fixed by screws 168 at the end .of the side bar 111.and a channel portion including a base 169,-sides 170 and 171 and flange 172 and 17 3. The channel portion is fastened to the frame167 in any suitable manner as by screws, asshown in Fig. 37. The flanges 172 and 173 serve to engage end notches 174 and 17 5, respectively, formed in each address plate and the plates are thereby retained within the channel porticn. 1 The dischar e galley may be arranged to receive the address plates and retain them in a vertical stack. However, at a point further from its receiving end, the galley may be curved into a horizontal direction (see Fig. 1), in order to deliver the address plates in a horizontal row.

As the address plates leave the support bar 117 aspushed out therefrom by one of the pawls 155, they strike against a stop member 176 which is fastened to the end of the side bar 112 and at the same time drop a short distance into the discharge galley, the notches v174 and bein engaged by the flanges 172 and 17 3 The group of address mats that drop into the discharge galley are further depressed by a depressing arm 17 7 ,-wl1i ch is pivoted at 178 to the side frame 46, and which is actuated by a cam 179 fixed upon the rotating shaft 81 (Fig. 13). The arm 17 7 may be provided with a roller 180 for engaging the surface of the cam 179, and a coil spring 181 may serve to maintain the surfaces of the roller and the cam incontact with each other.

Although the depression arm 177 serves to pack the address plates very compactly in the discharge galley, the stack of plates tends to expand upwardly when the arm is raised. To prevent this expansion, stop springs as at 182 are located in recesses 183 at each side of the galley in the side members 170 and 171. The stop springs at 182 are shaped so as to permit easy passage of the address plates downward, but obstruct their passage in the upward direction and hence serve to keep the plates tightly packed as appears in Fig. 14. It will be observed that the depressed edges 148 and 149 in conjunction with the longitudinal beads on the opposite sides of the mats 107 provide means by which a stack of plates will nest in the discharge galley. This tendency to nest will prevent any disalignment of the stacked mats such as would cause the sides of the notches 174 and 175 of a plurality of disaligned mats to cooperate to bind against the flanges 172 and 173 in the discharge galley, thereby preventing the progressive advance of the stack of plates under the action of the depression arm 177 (see Fig. 14).

Address impressions upon the wrapper pa per 40 are obtained from the mats 107 by means of an impression arm and mechanism C, as above stated. An impression is also made at the same time upon the proof strip paper by the mechanism at "H this impression being taken from the address mat which is in a position where it is about to be pushed forward under the impression mechanism C. This mechanism will now be described.

An impression arm 184 pivotally mounted upon a stationary shaft 185 (Fig. 11) is held in a desired predetermined position along this shaft by collars 186 and 187, each of which is provided with set screws (Fig. 2). The fixed shaft 185 is mounted upon extensions 188 and 189 (Fig. 5), formed respectively upon the supporting brackets 109 and 110. One end of the arm 184 is provided with a platen 190, at tached thereto by means of a grooved clamping block 191, which is adjustably fixed to the arm by screws 192. The platen 190 may be reinovably slid into a suitable groove 193 in the face of the clamping block 191. The other end 194 of the impression arm 184 is held by a spring 195, in contact with a cam arm 196, which is clamped by a split hub 197 to a shaft 198. The spring 195 is attached to the impression arm and the cam arm by means of pins 199 and 200, respectively, as shown. The shaft 198 may be rotatably mounted in suitable bearings 201 and 202 in the side frames and 46, respectively, and may be oscillated therein by means of a crank member 203, which in turn is operated by a cam 204 (Figs. 2 and 6). The crank member 203 is keyed to the shaft 198 and makes contact with the cam 204 by means of a roller 205, rotatably mounted at its lower end. The roller 205 is maintained in contact with the cam 204 by means of a coil spring 206, which is attached at one end to a lug 207, formed upon the crank member 203 and at the other end to a pin 208 fixed in the side frame 45. The cam 204 is rotated by the shaft 81, heretofore referred to and during its rotation the crank member 203 is pushed outwardly against the tension of the coil spring 206, thereby causing the cam arm 196 to push upwardly the end 194 of the impression arm 184, which results in a downward movement of the platen 193, at the other end of the impression arm. The platen 193 presses the proof strip paper firmly against one of the address mats 107, which happens to be positioned at this point at the time and leaves an impression from an ink ribbon 209, upon the wrapper paper.

An address impression arm 210 is constructed in a manner similar to the impression arm 184, above described and hence will not be described in detail. The address impression arm is also supported upon the shaft 185 and operated by the shaft 198 in a man ner similar to the operation of the impression arm 184. Address impressions are taken from an ink ribbon 211.

To provide for a return address or any other information, for example, post office permits and serial numbers, which are to be the same on a large number of the wrappers, a third impression arm 212 is provided and is actuated by the shaft 198 in a manner similar to the actuation of the impression arms 184 and 210. The arm 212 is also supported upon the shaft 185. The return address impression is taken from a stationary address plate 213 mounted upon a block 214 which in turn is supported by a cross member 215 extending from the bracket 110 (see Fig. 11). The address plate 213 may, if desired, be of the same type of construction as that illustrated in Figs. 3 and 4, or it may be varied in design to suit particular requirements and is preferably s-lidably mounted as shown upon the block 214. The path along which the proof strip passes from rolls G through the machine to the proof strip winding mechanism at I will now be described in detail.

The proof strip roll G is mounted upon brackets as shown at 216, attached to the side frames 45 and 46. The proof strip paper 217 is pulled from the stock roll G by proof strip feed rollers 218 and 219 (Fig. 11), over the guide bars 220 and 49, address mat guideway 50, over a guide rod 221 and between the rollers 218 and 219 and is then wound around a roller 222 by a mechanism which will be hereinafter described.

The proof strip feed roll 218 is rotatably mounted upon the shaft 54, which is suitably journaled in the side frames 45 and 46, as shown at 223 in Fig. 20, the shaft being retained in position in the ournal by means of a s sash a a 22 Pr de wi h et screws as shown. The proof strip feed roll 218 preferably consists of two separate disc rollers 225 and 226, as indicated in Fig. 20, between which is formed a hub 227, which is engaged by a brake member 228 fixed to the guide rod 221. The brake member-228 is provided at its end with alayer of friction material 229, such as wood, and serves to normally prevent the rotation of the feed roll 218. The feed roll 218 is also provided with a ratchet 230, which is engaged by a pawl 231 pivoted upon a pawl crank member 232. The pawl crank member232 is provided with a hub portion surrounding the shaft 54 and a pair of lugs 233 to which a connecting rod 234 is pivoted at a pin 235, The proof strip feed roll 218 then is rotated by the action of the cam 204 upon theconnecting rod 234 (see Figs. 2 and 6), the connecting rod being pivoted at 235 to a lever 236, which in turn is pivoted to the side frame upon the guide rod 49 and is arranged to engage the surface of the cam 204. The lever 236 is retained in contact with the surface of the cam 204 by means of a coil spring 237, which is fixed to the side frame 45, as shown. From the above described construction, it will appear that upon each revolution of the cam 204, the connecting rod 234 will be oscillated and the pawl 231 will rotate the ratchet 236 through an angle corresponding te the spacing of two adjacent teeth upon the ratchet. This amount ofrotation will serve to advance the proof strip paper the desired amountfor the next address. The brake member 228 prevents over-rotation of the feed rollers and conseqi ent waste of the proof, strip paper, since rotation occurs only when the roller 218 is pushed by the pawl 231. j,

Theproof strip paper 217 is pressed firmly against the, roller 218 by the roller 219, which is mounted upon an arm 238 supported upon a shaft 239., which in turn is j'ournaled in the side frames 45 and 46. The arm 238 is provided with a pair of lugs 240 embracing the shaft 239 and between which a spring 241 is located for the purpose of pressing the roller 219 firmlyinto contact with the roller 218. The spring 241 is fixed at one end by means of apin 242 to the shaft 239 while its other end bears against the arm 238, as shown in Fig. 20. The tension of the spring 241 may be adjusted in order to adjust the pressureupon the roller 219 means of a handle 243 fixed to the shaft 239. The handle 243 may be turned until the spring 241 is adjusted to give the desired pressure upon the arm 238 and then the shaft may. be fixed in position to the frame 45 by tightening a; set screw 244'.

. The receiving roller 222 is rotatably mounted upon a shaft 245 (Fig. 21) The shaft 245 is fixed at one end to a cradle member 246 ivoted at 247 on the side frame 45 by means of a stub shaft 248. Also rotatably mounted upon the shaft 245 is a friction roller 249 rotated by frictional engagement with a motor driven roller 250, which is mounted upon a shaft 251 fixed in side frame 45, and is rotated by a belt 252 and pulley 252 driven from the motor L. The receiving roller 222 is provided with a pair of bearing members 253 and 254 through which the shaft 245 extends. The receiving roller 222 is rotated by'frictional engagenientof its bearing member 254 with friction bands 255 and 256 secured to lugs 257 formed upon the friction roller 249 (Figs. 21 and 22). The friction bands 255 and 256 comprise strips of friction material 258, such as canvas, together with reenforcing strips of metal 259, which are secured at their ends by screws 260 to the lugs 257. Carried by another end 261 of the cradle 246 is another fixed shaft 262, upon which is rotatably mounted a re-winding roller 263. similar in construction to the receiving roller except that a bearing member 264 extends to the end 261 of the cradle 246 and has fixed thereon a friction roller 265 for engagement with the motor drivenroller 250/ A handle member 266, as best shown in Fig. 6, is pivoted upon the shaft 247 and is provided with oppositely projecting lugs 267 and 268'containing recesses engaged by coiled compression springs 269 and 270, respectively, the other ends of thehsprings en'- gag'ing the recessed portions 271 and 272 respectively formed upon the cradle 246. The turning movement of the handle 266 is limited by a pin 273 fixed in 2. lug 274 formed on the side frame 45. The pin engages a slot 275' formed in the handle member 266.

The object of the l e-winding roller 263 is forthe purpose of re-winding the proof strip paper 217 in order that the first address printed thereon will be at the outside layer upon the roller as finally wound, it being understood that as the proof strip paper is wound upon the receiving roller 222, the addresses thereon will be available in the inverse order from that desired, the first part of the list of addresses being wound upon the inside of the roll. Inmost cases it would be very inconvenient to use a proof strip wound in this manner and in order to eliminate this inconvenience, the above described r e-winding roller has been provided.

When it is desired to use the re-winding roller 263, the handle member 266 (Figs 6 and 21) is shifted upon the shaft 247 until the pressure of the spring 270 against the cradle 246 is sufficient to turn the cradle about the shaft 247 sufficiently to remove the friction roller 249 from contact with the motor driven roller250 and-to raise the friction roller 265 into contact with the motor driven roller. The outer end of the proof strip paper 217 as wound upon the roller 222 is secured to-the re-winding roller 263 and the entire roll of proof strip may be rewound thereon thus forming a roll in which the addresses are wound in the proper order.

In the re-winding operation it is very desirable to produce firmly wound roll. In order to accomplish this end, the friction roller 249 is held stationary in respect to the cradle 2&6 by inserting a suitable pin 276 through the holes 277 and 278 formed respectively in the cradle frame and in the roller, as shown by the dotted lines in Fig. 21. Since the friction roller 219 will now be stationary, the receiving roller can only revolve by the slipping of the bearing 25% between the friction bands 255 and 256, which act as brakes for preventing over-rotation of the receiving roller. Accordingly, the rewinding roller 263 must pull the proof strip paper 217 from the receiving roller against the holding power of the friction bands 255 and 256, and thus a very firmly wound roll results from the re-winding operation.

The proof strip paper 217 is secured to the rollers 222 and 263 beneath clip rods 279, as indicated in Fig. 23. One end of the clip rods fits tightly into a suitable hole 280 formed in the end of the roller and the other end 281 fits snugly in a suitable groove 282 in the periphery of the roll on which the proof strip is secured. The end of the proof strip is inserted in the groove 282 and is clamped therein by the clip rod 279. Nith this type of retaining means, when it is desired to unwind the paper from the spools, the end of the paper is automatically released when the spool becomes completely unwound.

The mechanism for operating the various inking ribbons will now be described. The proof strip impressions are taken from the inking ribbon 209; address impressions are taken from the ribbon 211 and the return address impressions from a ribbon 283. The ribbons 209 and 211 may be wound from spools 284 and 285 onto corresponding spools 286 and 287 and after the ribbons have passed through the machine in this direction they may be wound back again upon the spools 284- and 285, if desired. (See Figs. 5 and 11.)

A cross bar 288 fired in the side frames 45 and 416 has mounted thereon a bracket 289, having oppositely projecting arms 290 and 291, at the ends of which spool shafts 292 and 293, respectively are mounted. Another bracket 29 2 similar to the bracket 289 serves to support a shaft 295, upon which a spool 296, for the return address ink ribbon, is mounted. he bracket 29-1 is provided with oppositely extending arms, each carrying a shaft and spool in a manner similar to the bracket 289, as will be readily understood although but one of the arms is shown in Fig. 5.

All three of the ribbons 209, 211 and 283 follow similar paths from one set of spools to the other. The path of the ribbon 209 is typical and hence will be described in further detail. As the ribbon 209 leaves the inner side of the spool 284, (see Fig. 11), it passes over a pair of guide rods 297 and 298, located just beneath the path of travel of the paper strips and 217. The guide rod 297 may loosely rest in notches 297 formed in the brackets 209 and 210, (as indicated in Fig. while the guide rod 298 may similarly rest in notches 298 formed in the cross bar 215. Between the guide rods 297 and 298, the ink ribbon passes over the address mat guideway 50. The ribbon rests upon the top of the address mats but beneath the paper strips and 217. Hence when pressure is applied by the impression platens, impressions are taken on the under surface of the paper strips from the ink ribbons. From the guide rod 298, the ribbon 209 passes to the inner side of the spool 286 and is wound' thereon.

The mechanism for operating the spools comprises an oscillating shaft 299, ournaled in the side frames and 16 and held against longitudinal movement therein by the collars 300 and 301, this shaft being oscillated by the forked arm 302, fixed thereto. The forked arm 302 embraces an eccentric cam 303 fixed to the rotating shaft 81, (Figs; 5 and 6). The spools 284i and 286 and the corresponding spools for the return address ribbon 283 are provided with flanges, as at 304, having ratchets at their peripheries, which are engaged and operated by pawl mecha nisms 305 and 306, as indicated in Fig. 5. The pawl mechanisms 305 and 306 are of similar construction and hence the mechanism 305 only will be described.

A lever 307 is fixed to the shaft 299 by a split clamping hub 308 and is provided at its upper end with a double pawl member 309, pivoted at 310 and provided with oppositely projecting pawls 311 and 312 for.

engaging respectively the ratchet flanges upon the spools 28d and 286. The pawls 311 and 312 are so mounted that but one of them at a time can make contact with one or the other of tee ratchets. The ratchet of the spool upon which it is desired to wind the ribbon is placed in engagement with the corresponding pawl and the pawl is maintained in engagement with the ratchet by the coil spring 313, having one end attached to the pawl member and the other end attached to the lever 307.

The pawl member 309 may be turned so that a pawl will contact with the corresponding ratchet and in so doing the coil spring 313 will be turned into a biased position, such that the pawl member will remain in the desired position. Each oscillation of the shaft 299 by the action of the cam 303 and the forked arm 302 therefore results in the turning of the rib-
